Official basis (Method): ISTA Rules 2026 Chapter 6 is the relevant viability framework. Species specific evaluation and the full current chapter are required; do not infer germination performance from colour alone.
Procurement note: ISTA confirms the tetrazolium chapter; species-specific preconditioning, cutting and interpretation determine the final supplies.
